    Clutch Couplings and Clutches

    G

    Description

    Dynacorpclutches are used to control loads that are belt, chain, or gear driven. Clutch couplings are usedto control and couple in-line shafts between the prime mover and the load. Dynacorpclutches and clutchcouplings are available for a wide variety of industrial applications.

    The purpose of this kit is to hold the armature plate in contact withthe friction face to reduce pull-in time. It is recommended wherethe engagement time is critical; usually high cycle rate applicationswith the D2950 control. Also use this kit when a slow start or stopis required with the D2750 control. Since the friction surfaces arealways in contact a rubbing noise is created. The design of your

    machine may increase or decrease this noise.
